IMPROVED DEVICE FOR SEPARATING SHOT.

Specification forming part of Letters Patent No. 52,003, dated January9, 1866.

To all whom it may concern Be it known that I, WILLIAM ANTHONY SHAW, ofthe city and State of New York, have invented, made, and applied to usea certain new and useful Improvement in the Manufacture of Drop-Shot;and I do hereby declare the following to be a full, clear, and exactdescription of my said invention, reference being had to the annexeddrawings, making part of this specification, wherein- Figure l is avertical longitudinal section of my apparatus for assorting the shot,and Fig. 2 is a cross-section of one of the screening-cylinders and thetrough below.

Similar parts are designated by the same letters.

In the manufacture of drop-shot it becomes necessary to separate theimperfect shot from those that are globular, and also to assort theglobular shot according to their sizes. These operations have usuallybeen performed by costly hand-labor, and there has been no continuity inthe operations,but a series of chargin gs and dischargin gs by hand. Forinstance, the shot as they are discharged from a rotary polisher aretaken, a scoopful at a time, and scattered on an inclined table, and theattendant with a wide brush sweeps them up the incline, then raising hisbrush the globular shot roll down and so he proceeds until finally theimperfect shot are swept up over the highest edge of the incline into areceptacle. The globular shot are next placed in a hopper, a givenamount forming a charge. This hopper is upon a rocking frame containingdrawers with screen-bottoms to assort the sizes, and these drawers haveto be emptied byhand from time to time into receptacles or bins.

The object of my invention is to produce a continuously-operatin g orautomatic separator and assorter for shot or balls, whereby the shothave only to be supplied at the upper end of the machine, and from therethey proceed onward and downward and are separated, the imperfect onesbeing thrown out and the globular ones being assorted according to size.This is effected by a series of inclines combined with transversereceptacles at their ends, said inclines being set in oppositedirections, so that the momentum of the shot is checked in passing fromone table to the other, and the transverse receptacles receive theimperfect shot, which, in consequence of not being true globes, do notroll with sufficient velocity to cause them to be projected over thesaid transverse receptacles, and from these separating inclines the shotpass into and. through separating and assortin g screens, the differentsizes of shot being delivered into bins or receptacles provided forthem.

In the drawings, a is aframe-work, of suitable size, sustaining theinclined separatingplanes Z1 0 d c. There may be more or less in numberof these inclines, and they may be made adjustable in their inclination.These inclines are to stand at opposite inclinations in order that theshot rolling off the lower end of one must stop, and thence commence toroll in the other direction on the next. This prevents the shotacquiring too great velocity, and-also produces a pause wherein animperfect shot will turn upon its flattest side, and hence thereafterroll or slide more slowly than would be the case if the momentum werenot checked. Across the lower ends of the respective inclines aretroughs or receptacles f, placed with their upper edges in such aposition relatively to the edge of the incline that those shot that areglobular will, in rollin g down, acquire a sufficient velocity to passover this edge of the trough to the incline below, while those that arenot globular, and hence acquire less velocity, fall into the receptacleor receptacles f at some stage of the successive operations. It is bestto have the first inclines at a greater angle than the latter ones, inorder that the angular pieces first separated may not remain on thefirst incline. The shot are scattered upon the upper incline from theend of a spout or hopper, and pass from the bottom of the last inclineinto the hopper g, that conveys them to the first of a series of rotaryscreens, which screen It is form ed cylindrically or slightly conical,and of perforated sheet metal or other material, set upon arms from aremovable shaft, 00, at one end of which is a square or socket, 3setting upon a similar coupling that connects with a short shaft rotatedby the wheel at, driven by competent power. The shot that pass throughthe meshes of the sieve it fall on an incline, m, and. roll into thenext hopper q, and pass into the next sieve, '5, while those that remainwithin the sieve h are allowed to run out thereof into a receptacle, t,or an inclined bucket, 1, may be fitted within the sieve adjacent to theinterior flange at the end, so as to lift the shot and throw them outover said flanged end into t. I have shown a series of these sieves orscreens, h i 70 Z, with corresponding inclines m a 0 12 below them,conveying the shot to the hoppers q r s respectively, while the shotthat do not pass through the sieves are delivered in the assortedcondition into the respective receptacles t u v w.

The screens h 15 70 I may be sustained at the end opposite the couplingsy by any suitable means. Ihave, however, shown pointed screws 2 2 takingcavities in the ends of the shafts respectively, in order that thescreens may be removed with facility and others with different sizes ofmeshes substituted, so as to suit the size of shot that is beingassorted.

I prefer that the top screens should have the largest meshes, so as toretain the largest shot and let all the other shot pass through; but ifthe screen with the smallest meshes is placed at the top the respectivebins or receptacles t a o w will have to be placed where the hoppers q rs are shown, so that the shot retained in the screens will be emptiedinto the hoppers, while the smallest shot are taken off successively bythe inclines m n 0 p below to the respective receptacles.

What I claim, and desireto secure by Letters Patent, is

1. A series of revolving screens for assorting the shot, in combinationwith the inclines and receptacles, substantially as specified.

2. The method herein specified of assorting shot and delivering thedifferent sizes into receptacles by mechanism, substantially asspecified.

3. The combination of a series of inclines for separating the imperfectshot, as set forth, with a series of screens for assorting the sizes ofthe shot, all constructed and arranged substantially as set forth.

In witness whereof I have hereunto set my signature this 5th day ofAugust, A. D. 1865.
